All about bicycles, electric-assisted bikes, technology and safety in the press

The most common safety risks that we come across in our daily work around bicycle safety, technology and operating instructions are also published by us in articles in the leading German special-interest magazines TOUR (Europe's road bike magazine no. 1), BIKE (Europe's mountain bike magazine no. 1), MYBIKE and EMTB in order to make this information, which is important for the industry, available to a wider public.

For many years now, the Eurobike Show Daily, trade fair magazine of the annual Eurobike Show, has also given us the opportunity to publish our view of major developments in the cycle industry in full-page articles.

We also speak regularly in independent expert presentations about all areas of bicycle technology and the bicycle market. In addition, we are quoted by further special-interest magazines of the industry and the trade as well as increasingly by radio and television in their media reports, which shows us that we are spot on with our advice. The section "News" informs you about the latest news from our specialist areas. The reports and publications of this section are listed chronologically or according to areas of interest., 2023/05/08

Publication of new guidelines for parts replacement on e-bikes 25/15.5 and fast e-bikes (45/28)

What are bicycle workshops allowed to change on electric bicycles and for which components and accessories do they need the approval of the vehicle manufacturer or the system provider? Answers to this question are provided by guidelines that have now been updated.

Both the replacement of wearing parts as well as individual adjustments on bicycles have long been a matter of course. In the case of e-bikes it is necessary to have a closer look. Certain components may not be replaced just like that. One reason is that e-bikes with motor assistance of up to 25 kmh/15.5 mph must comply with the requirements of the CE conformity needed EU-wide. This certificate is a guarantee for consumers that the product complies with the legal requirements. If parts are replaced or newly installed that may impair durability or change the riding behaviour, this can lead to an expiration of CE conformity and the loss of warranty of the manufacturer. In addition, speed pedelecs with a motor assistance of up to 45 kmh (28 mph) (fast e-bikes / speed pedelecs) require particular attention. They are considered motor vehicles and therefore subject to particularly strict regulations. As is the case with motorcycles or motorcars, the law provides specific regulations.

To be on the safe side with this complex topic, leading institutes and associations have compiled their expertise in a “Work group parts replacement on e-bikes and speed pedelecs”. In two tables for 25/15.5 e-bikes (EPAC/EAPC) and the speed class of 45/28 e-bikes (speed pedelecs) the parts replacement is treated in different categories.


The following institutes and associations are involved in the work group parts replacement on e-bikes and EPACs/EAPCs: The umbrella organization for German industry guilds BIV, TUEV Rhineland,, the German service and bicycle association VSF, Zedler-Institut, German bicycle association ZIV.
